1. A method comprising: receiving, from a client device, a query that includes one or more query terms; identifying a set of search results based on the received query; providing a search results page that includes a search result for a particular document that has a plurality of different pages in the particular document; receiving data indicative of user interaction with the search result in the search results page, wherein the search result corresponds to the particular document; and providing, after receiving the data indicative of the user interaction, a publication excerpt page for display on the interface of the client device, that, when rendered by the client device, causes the client device to obtain, from a network location that the publication excerpt page identifies for the particular document, image data for an image of at least a portion of a page of the particular document, wherein the image includes at least one query term of the one or more query terms in a first portion of the image that has been visually distinguished from other portions of the image containing other terms on the page; wherein the publication excerpt page includes a plurality of links that each reference a different page of the particular document.

2. The method of claim 1 wherein the plurality of links includes one or more links that each reference a predetermined page of the particular document independent of user interaction with the particular document.

3. The method of claim 1 wherein the plurality of links includes one or more links that each reference a page of the particular document that a user of the client device previously accessed.

4. The method of claim 1 , further comprising: determining one or more third-party content items that are associated with (i) the particular document, (ii) the one or more query terms, (iii) a provider of the particular document, (iv) an author of the particular document, or (v) a combination thereof; and providing an advertisement for display on the publication excerpt page for the third-party content item.

5. The method of claim 1 , wherein the publication excerpt page includes a reference to the image file that is configured to cause the client device, upon rendering of the publication excerpt page by the client device, to (i) submit a request for the image file to a network location identified by the reference, (ii) receive the image file from the network location in response to the submitted request, and (iii) display the image file.

6. The method of claim 1 , wherein the image file comprises image data obtained by optically scanning at least a portion of the particular document.

7. The method of claim 1 , wherein one or more instances of the at least one query term in the image have been visually distinguished from other terms in the image.

8. The method of claim 1 , wherein one or more instances of the at least one query term in the image have been visually distinguished from terms in the image that are not terms of the query.

9. The method of claim 1 , wherein the image is a page image, and the first portion of the image is an excerpt portion that includes the at least one query term, the first portion being visually distinguished by an indicator applied to the page image.

10. The method of claim 1 , wherein the at least one query term in the first portion of the image has been visually distinguished by highlighting the at least one query term.

11. A system comprising: one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising: receiving, from a client device, a query that includes one or more query terms; identifying a set of search results based on the received query; providing a search results page that includes a search result for a particular document; receiving data indicative of user interaction with the search result in the search results page, wherein the search result corresponds to the particular document that has a plurality of different pages in the particular document; and providing, after receiving the data indicative of the user interaction, a publication excerpt page for display on the interface of the client device, that, when rendered by the client device, causes the client device to obtain, from a network location that the publication excerpt page identifies for the particular document, image data for an image of at least a portion of a page of the particular document, wherein the image includes at least one query term of the one or more query terms in a first portion of the image that has been visually distinguished from other portions of the image containing other terms on the page; wherein the publication excerpt page includes a plurality of links that each reference a different page of the particular document.

12. The system of claim 11 , wherein the plurality of links includes one or more links that each reference a predetermined page of the particular document independent of user interaction with the particular document.

13. The system of claim 11 , wherein the plurality of links includes one or more links that each reference a page of the particular document that a user of the client device previously accessed.

14. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising: receiving, from a client device, a query that includes one or more query terms; identifying a set of search results based on the received query; providing a search results page that includes a search result for a particular document that has a plurality of different pages in the particular document; receiving data indicative of user interaction with the search result in the search results page, wherein the search result corresponds to the particular document; and providing, after receiving the data indicative of the user interaction, a publication excerpt page for display on the interface of the client device, that, when rendered by the client device, causes the client device to obtain, from a network location that the publication excerpt page identifies for the particular document, image data for an image of at least a portion of a page of the particular document, wherein the image includes at least one query term of the one or more query terms in a first portion of the image that has been visually distinguished from other portions of the image containing other terms on the page; wherein the publication excerpt page includes a plurality of links that each reference a different page of the particular document.

15. The computer-readable medium of claim 14 , the operations further comprising: determining one or more third-party content items that are associated with (i) the particular document, (ii) the one or more query terms, (iii) a provider of the particular document, (iv) an author of the particular document, or (v) a combination thereof; and providing an advertisement for display on the publication excerpt page for the third-party content item.
